prediction on when clementine uses the gun

Has it even been confirmed that season 2 will have the surviving characters of season1? I was more hoping that season 2 will have all new characters with their own stories, starting over at the outbreak.

That's what I think will happen, but I prefer something a little after the outbreak, like a year later, or something a little before where you can see it happening, versus while Lee was knocked out through it all---Why do you care so much about my signature?
